android - retrofit.RetrofitError：只允许使用一种HTTP方法。实测：PUT和PUT

Question

这是我的错误：

D/Retrofit: java.lang.IllegalArgumentException: Sales.updateDeliveryLine: Only one HTTP method is allowed. Found: PUT and PUT. 
                       at retrofit.RestMethodInfo.methodError(RestMethodInfo.java:123) 
                       at retrofit.RestMethodInfo.parseMethodAnnotations(RestMethodInfo.java:155)

                       at retrofit.RestAdapter$RestHandler$2.obtainResponse(RestAdapter.java:278)

                       at java.lang.Thread.run(Thread.java:818) 

这是我在Android Studio中的代码：

@PUT("/salesinsight/GetDeliveryScheduleLineRow/") 
     public void updateDeliveryLine(@Path("id") int id, @Body API_DeliveryScheduleLines api_deliveryScheduleLines, 
             Callback<API_DeliveryScheduleLines> callback); 

这是我在网络API代码：

// PUT: api/GetDeliveryScheduleLineRow/5 
    [ResponseType(typeof(void))] 
    public IHttpActionResult PutDelivery_Schedule_Lines(int id, Delivery_Schedule_Lines delivery_Schedule_Lines) 
    { 
     if (!ModelState.IsValid) 
     { 
      return BadRequest(ModelState); 
     } 

     if (id != delivery_Schedule_Lines.ID) 
     { 
      return BadRequest(); 
     } 

     db.Entry(delivery_Schedule_Lines).State = EntityState.Modified; 

     try 
     { 
      db.SaveChanges(); 
     } 
     catch (DbUpdateConcurrencyException) 
     { 
      if (!Delivery_Schedule_LinesExists(id)) 
      { 
       return NotFound(); 
      } 
      else 
      { 
       throw; 
      } 
     } 

     return StatusCode(HttpStatusCode.NoContent); 
    } 

请帮我解决我的问题。我不知道该怎么办。每次尝试更新错误时都会显示。提前致谢。

首先在你的PUT方法中，你传递id为Integer。但是你没有在你的API路径中提到缺少的id。希望能帮助到你。

@PUT("/salesinsight/GetDeliveryScheduleLineRow/{id}") 
    public void updateDeliveryLine(@Path("id") int id, @Body API_DeliveryScheduleLines api_deliveryScheduleLines, 
            Callback<API_DeliveryScheduleLines> callback);
